I installed proper resistors and aligned the horizontal circuits; I had to replace the 47K resistor in series with the drive control with a 22K and now I can eliminate the drive line. HV is 15-16kV maximum when the drive line is gone, though. Horizontal output cathode resistor voltage was about 1.6 volts. This set also has some intermittent issues with the video circuits. (Originally, I feared that it was problems with the blue gun of the 15GP22, but it is doing similar things on my test jig's CRT.) My main goal with this set right now was to confirm the condition of the 15GP22, and it is good. The set still needs to have a lot of other resistors re-replaced as well as a number of peaking or other coils. I have other non-TV work that needs to get done, so I am going to put this set off for a while until I get caught up with some of those projects.
